IMPROVEMENT IN STEAM FIRE-ENGINES.

Specification forming part of Letters Patent No. 143,750., dated October 2l, 1873; application iiled August 27, 1873.

To all whom it may concern:

Beit knoWn that I, WILLIAM C. DAvoL, Jr., of Fall River, of the county of Bristol and State of Massachusetts, have invented a neW and useful Improvement in Steam Fire-Engines, and do hereby declare the same to be fully described in the following specification and represented in the accompanying draW- ing, Which exhibits a perspective side eleva tion of a steam tire-engine provided With my addition or invention.

Most if not all such engines have upright boilers, and, While at Work, discharge the ashes and cinders of the iire-place directly upon the ground or pavement underneath the boiler, and between the next adjacent Wheels of the carriage, in consequence of Which the said Wheels are very liable to become. scorched, smoked, or burned more or less. To avoid the injurious effects of the heat of the Waste coals and ashes, resort has generallybeen had to plates ofiron or metal, or to boards set up against the inner sides of the Wheels, so' as to intercept the heat and smoke, and deiiect such, The object of my in' vention is to prevent such injurious results to the Wheels from the heat of the Waste products of combustion of the furnace; and for such purpose l extend from the Waste-educt or eductionchest A ofthe engine, a pipe or conduit, B, to open into a tubular ring, C, arranged horizontally underneath the boiler, or below and around the passage by Which the ashes and coals esA cape from the furnace to the ground, such ring C being perforated with numerous holes, so arranged as to cause, While the engine may be at Work, Water to bedischarged directly upon the spent products of combustion on the ground, and also about such and upon the Wheels Where theymay be liable to be injured by the heat.

By such means the Wheels maybe effectually protected from the heat and smoke, and all necessity of deiiectors is overcome. To the conduit B I- usually apply a cock provided With a hand-Wheel, a, such being to regulate the discharge of Water from the pipe or y ring. Thus, While the engine may be forcing Water from the educt, or there may be Water under pressure in the fountain or chest, part of such Water may be thrown or discharged into and through the ring.

What, therefore, I claim as my invention 1s- The combination of the conduit B and fo-v raminous or perforated ring C With the firebox of a steam .fire-engine, all being substantially as set forth, and for the purpose of protecting its Wheels, as speciiied.
